ADJUSTABLE CURTAIN-BRACKET.

Specification of Letters Patent.

Patented July 24, 1917.

Application filed October 11, 1916. Serial No. 125,080.

To all whom it may concern:

Be it known that I, RoBnR'r BROWNE, a citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvements in Adjustable Curtain- Brackets, of which the following is a specification.

This invention relates to improvements in adjustable and extension window shade brackets, and has for one of its objects to provide asimply constructedfdevice wherein the claims; and in,the drawings illustrative of the preferred embodiment of the invention Figure 1 is an elevation on a relatively small scale of the upper portion of a window with the improvement applied.

Fig. 2 is a front elevation of one of the bracket devices. 6

Fig.3 is a plan view of the improved device with the wall of the building in section on the line 33 of Fig. 1 and with a portion of a curtain roller attached.

Fig. 4 is an end elevation of'one of the roller supporting devices with the windowframe in section on the line H of Fig. 1.

Fig. 5 is a transverse section on the line 5-5 of Fig. 2.

Fig. 6 is a detached perspective view of one of the curtain roller supports.

Fig. 7 is a front elevation of one of the improved devices with a roller winding attachment.

Fig. 8 is an end elevation of the form of structure shown in Fig. 7.

Fig. 9 is a plan view of the structure shown in Figs. 7 and 8, with a portion of a curtain roller attached.

Fig. 10 is an enlarged sectional detail of a portion of the structure shown in Figs. 7-8 and 9.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises in general coacting brackets adapted to be supported at the upper ends of the side portions of a window, doorway or like opening, and provided with means for adjustably supporting the journals of a curtain roller, so that curtain rollers of various lengths may be supported without detaching the brackets.

The brackets at each side of the window or door are substantially alike, and the description of one will sutfice for both. Each bracket device comprises a base plate, indicated at 10, and a housing or casing including a base portion 11, corresponding to and adapted to bear upon the base member 10, and an outwardly directed portion 12.

The portions l112 are pressed from a plate of metal, preferably brass or the like, and form a shell like structure, oblong in outline and provided with a relatively long slot 13 in its outer face. The slotted portion of the structure 12 is preferably inclined from the upper side, toward the base portion 11, as represented in Figs. 1 and 5.

The end walls of the portion 12 of the bracket are pierced to receive a threaded shaft or rod 11, the rod having a milled finger wheel 15 on its outer end, externally of the bracket, to enable the rod to be rotated.

Mounted upon the rod 1 1 is a roller support, represented as a whole at 16, and disposed at one end through the slot 13 and into the interior of the portion 12 of the bracket, the member 16 having a threaded aperture to receive the rod 14. The edges of the portion of the member 16, which is located within the shell portion 12 of the bracket are turned laterally as shown at 17, and correspond to and bear upon the upper and lower faces of the portion 12 of the bracket. By this means relatively large bearing faces are produced between the member 16 and the shell portion of the bracket, to increase the steadiness of the movements when the threaded rod 1 1 is rotated. If found neces sary the member 16 will be reinforced, or increased in thickness, as shown at 18 where the threaded aperture is produced.

The member 16 of one of the brackets is pierced with an elongated slot, represented at 19, to receive the flat journal at the spring end of the roller, while the aperture of the member 16 of the other bracket will be circular to receive the circular journal at the opposite end of the roller, in the usual man nor. The brackets are constructed rights and lefts, the bracket at the left being adapted to support the spring end of the roller, while the bracket at the right is adapted to support the other end of'the roller.

The base portions 1()-11 of the brackets are pierced to receive nails or screws, whereby the brackets are attached to the supportin g structure.

In Figs. 7-8 and 9 a bracket device is shown in which provision is made for winding the spring of the roller to increase or decrease the tension without detaching the roller from the brackets. In thisform of the structure the portions 10-11 and 12 and the threaded rod 14 are precisely the same as shown in Figs. 2 and 3.

In the form of structure shown in Figs. 7-8 and 9 the member 16 is replaced by a similar member slightly different in form and indicated at 20. The portion of the member 20, which is located within the portion 12 of the bracket is the same as that shown in Fig. 6, while the outer portion is pierced to receive a stub shaft 21, enlarged at one end and formed with a toothed disk or ratchet 22, and a socket 233, having an elongated cavity to receive the fiat journal atthe spring end of'the roller. The other terminal of the shaft 21 is adapted to receive a turning knob 24:, which may be threaded on the shaft 21, or otherwise secured thereto. By this means the shaft 21 together with the ratchet 22 and socket 23 is mounted for rotation in the member 20.

Gravity pawls 25-26 are pivoted to the member 20, and engage the ratchet from opposite sides, and coact with the ratchet to hold the roller yieldably from movement in either direction.

By this simple arrangement it will be obvious that the spring, of the roller may be wound up to increase its tension, without the necessity for removing the roller from'the brackets, and that the tension may be reduced or decreased, if required, by manually releasing the pawls and permitting the roller to rotate backward to any required extent. By this means the tension of the rollers may be easily controlled.

The parts of the brackets are constructed wholly of metal, and will preferably be of brass, aluminium or like non-corrosive metal.

Having thus described the'invention, what is claimed as new is: I

1. In a device of the class described, a bracket adapted to be supported from a window, a shaft mounted for rotation in said bracket and having asocket adapted to receive the spring end journal of a curtain roller, a ratcheted member carried by said shaft and bearing against the bracket at one side, a stop pawl carried by said bracket and engaging said ratcheted'member, and a combined shaft turning and holding member engaging said shaft and bearing against the outer face of the bracket, whereby the shaft is held from displacement longitudinally.

2. In a device of the class described, a bracket adapted to be supported froma window, a shaft mountedrfor rotation in said bracket and threaded at one end and having a socket at the other end adapted to receive the spring end journal of a curtain roller, a ratcheted'member carried by said shaft and bearing against the bracket at one side, a stop pawl carried by said bracket and engaging said ratcheted member, and a combined shaft turning and holding member threaded to engage the threaded end of the shaft and bearing against the outer face of the bracket, whereby the shaftis held from displacement longitudinally.

In testimony whereof I afliX my signature.
